1 Claim. (Cl. 215-38) The invention relates to a capsule for a bottle invention, may be provided preferably with lon or similar vessel, which is constructed in such gitudinal grooves or ribs which on pressure being a manner that it has a particularly simple smooth applied to the pressing block, penetrate into the exterior, that "it can. be fixed in a convenient bent-over capsule edge. Since these grooves or manner on a bottle as well as being removable ribs may have a different cross-section accordtherefrom' with the application of small force, ing to the indentations which are desired to be and that it is especially suitable for bottles the formed in the bent-over capsule edgeithey are not contents of'which are under high pressure. illustrated in the drawing, since their eventual The capsule according to the invention is esshape will be clear without being illustrated.
